I'm in the Knitting Doldrums

I'm not sure what the problem is, really. I have two WIP's. Although, I'm not sure you can call Arwen a WIP, since I mostly refuse to look at it. So I'm really only working on the Gryffindor scarf. And I have other projects to start. I really do. But... But. I don't really want to. It's not that I don't have yarn! Lord knows, I have plenty of yarn! Lovely, luscious, pettable, lay-down-and-roll-in-it, can't-stop-touching-it yarn. Then I look at patterns on Ravelry, in magazines, in books, in my giant pattern notebook, and nothing really says "knit me!". Oh, some of them sort of capture my interest, but then I'd want to modify. And I don't think modify is really part of my skill set right now. So I look at patterns on Ravelry, in magazines, in books, in my giant pattern notebook, and, well, nothing. There's a niggling thought in the back of my mind that perhaps my knitting obsession is over. And while it was longer-lived than most of my obsessions, I really don't want that to be the case. I guess what I'd like to know is: Has this ever happened to you? And what on earth did you do about it? HELP!!
